Radiator Chemicals

System chemicals to clean and protect your central heating radiators. When your central heating system is serviced anually, it is advised to put a system... cleanser in your system and run it through as per the instructions prior to draining down. This will remove any sludge and dirt build up and allow your radiators to perform more efficiently. Once this maintenance has been completed, top up the system and add in a fresh Inhibitor to stop corrosion building up. Remember to cut out the 3rd ingredient of rust... Air! Once topped up, and your system has pumped round for a while, make sure you bleed all radiators to remove any air in the system, and let your rads fully heat up. Dont forget to top up the boiler pressure once you have bled the system.
